Description

Technical Field

[0001] This application relates to the field of tire production equipment technology, and in particular to an automatic detection and control device for the post-tire shaping circumference. Background Technology

[0002] Post-conversion tire shaping is a crucial step in ensuring consistent tire quality, especially in the production of all-terrain vehicle (ATV) tires. Precise control of the outer diameter directly impacts product performance and lifespan. Due to the design of ATV tires, natural cooling after vulcanization and subsequent re-inflation can lead to significant variations in the outer diameter, resulting in defective products that fail to meet usage requirements. Therefore, post-conversion shaping is necessary after vulcanization, while the tire is still warm. Cooling and shaping must be performed within a controlled circumference range to ensure uniformity in the final service circumference of the product.

[0003] Currently, in related technologies, to solve the dimensional control problem during the tire post-forming process, sensors are typically used to detect the tire's dimensions, ensuring that the sensor measurements are within a specified range. To accommodate the testing needs of different tire sizes, the sensor position is usually manually adjusted to keep the measurement results within the specified range.

[0004] However, since the sensor and the tire need to be relatively fixed during measurement, the sensor needs to be manually adjusted repeatedly after each change of tire size to correct the tire circumference. This process is tedious and wastes time and manpower.

[0005] The aforementioned technologies suffer from the drawback of having a cumbersome process for detecting the circumference of tires of different specifications. Utility Model Content

[0006] To improve the cumbersome process of tire circumference detection for different specifications, this application provides an automatic tire post-shaping circumference detection and control device.

[0007] The automatic tire rear shaping circumference detection and control device provided in this application adopts the following technical solution:

[0008] An automatic tire circumference detection and control device includes: a support mechanism; a clamping mechanism disposed on the support mechanism for clamping a tire and sealing the tire bead; a pneumatic mechanism for inflating or extracting air from the tire; and a detection mechanism comprising a first drive assembly, a second drive assembly, a detection element, and a measuring assembly, wherein the first drive assembly and the second drive assembly are both disposed on the support mechanism, the detection element is slidably connected to the support mechanism, and the detection element is disposed on one side of the clamping mechanism. Both the first drive component and the second drive assembly cooperate with the detection component. The second drive assembly is used to drive the detection component to move towards the clamping mechanism, so that the detection component abuts against the tire tread. The measuring component is located on the support mechanism and on the side of the detection component away from the clamping mechanism. The measuring component is used to measure the horizontal distance between itself and the detection component. The first drive assembly is used to drive the detection component away from the clamping mechanism and reset it to the initial position. The control mechanism includes a control component that is electrically connected to the measuring component and the pneumatic mechanism.

[0009] By adopting the above technical solution, automatic detection and control of tire circumference after shaping is achieved. The support mechanism provides a stable foundation for the entire device, ensuring precise positional relationships among components during operation. The clamping mechanism firmly holds the tire while sealing the upper and lower bead openings to prevent air leakage and ensure accuracy during detection. The pneumatic mechanism performs tire inflation and deflation operations to adjust the tire circumference. The second drive component in the detection mechanism allows the detection element to precisely contact the tire tread, while the first drive component enables the detection element to reset for tire replacement, improving the automation of the detection element's movement and eliminating the need for frequent adjustments to the measuring components. The measuring component acquires the horizontal distance between itself and the detection element in real time, thus accurately measuring the tire circumference. The control mechanism, through electrical connection between the measuring components and the pneumatic mechanism, achieves automatic data acquisition and processing, and automatically adjusts the tire's internal air pressure based on the detection results to ensure the tire circumference meets requirements. The overall solution reduces human intervention, simplifies operation, improves detection accuracy and efficiency, and reduces the defect rate.

[0010] Optionally, the first driving component includes a slide rail, a slider, a moving drive component, and a toggle component. The slide rail and the moving drive component are both disposed on the support mechanism. The slider is slidably connected to the slide rail. The toggle component is connected to the moving drive component. The moving drive component is used to drive the toggle component to move. The toggle component is disposed on one side of the slider. The toggle component is used to toggle the slider. The detection component is disposed on the slider, so that the moving drive component drives the detection component to move away from the clamping mechanism.

[0011] By adopting the above technical solution, the cooperation between the slide rail and the slider enables the detection component to move horizontally stably, ensuring the accuracy of the detection process. The combined use of the moving drive component and the actuating component achieves precise control of the slider, allowing the detection component to be reset to its initial position via a mechanical structure when tire replacement is required. This design eliminates the need for manual adjustment, improves detection efficiency, reduces human error, and ensures the automation and reliability of tire circumference measurement.

[0012] Optionally, the moving drive is a rodless cylinder.

[0013] By adopting the above technical solution, the moving drive component uses a rodless cylinder, which enables precise linear motion control, ensuring smooth movement of the inspection component as it approaches or moves away from the clamping mechanism. The rodless cylinder design eliminates the structural limitations of traditional cylinder piston rods, resulting in higher space utilization and improved system compactness and stability. Furthermore, the rodless cylinder offers high response speed and positioning accuracy, contributing to improved inspection efficiency and the accuracy of inspection results, thus better meeting the precision and automation requirements of the automatic tire circumference inspection and control device.

[0014] Optionally, the support mechanism includes a gantry frame, a support frame, and a mounting plate. The gantry frame is used to support the clamping mechanism. The lower end of the support frame is connected to the bottom end of the gantry frame. The mounting plate is located at the upper end of the support frame. The slide rail is located on the mounting plate. The moving drive component is located on one side of the mounting plate and at the upper end of the support frame, so that the actuating component can cooperate with the slider.

[0015] By adopting the above technical solution, the support mechanism consists of a gantry frame, a support frame, and a mounting plate, forming a stable structural foundation and ensuring the operational reliability of the entire device. The gantry frame is used to mount the clamping mechanism, ensuring the tire is stably fixed during the inspection process. The cooperation between the support frame and the mounting plate provides mounting positions for the slide rail and the moving drive component, enabling the first drive assembly to accurately move the inspection component, thereby achieving accurate contact and measurement of the tire tread. This structural design effectively improves the automation and accuracy of the inspection, while reducing errors caused by human intervention, and enhancing the stability and consistency of the post-forming circumference inspection.

[0016] Optionally, the second drive assembly includes a counterweight, a flexible component, a first guide, and a second guide. The first guide is disposed on the gantry frame, and the second guide is disposed on the mounting plate. The first guide and the second guide are horizontally distributed. The counterweight is connected to the first end of the flexible component, and the second end of the flexible component is connected to the slider. The flexible component is sequentially wound around the first guide and the second guide, so that the vertical downward movement of the counterweight drives the slider to move horizontally toward the clamping mechanism.

[0017] By adopting the above technical solution, the cooperation between the counterweight and the flexible component enables the automatic and reliable contact of the detection component with the tire tread, ensuring the accuracy of the measurement and improving detection efficiency and precision. The horizontal distribution design of the first and second guide components makes the transmission of the flexible component more stable and reliable, avoiding errors caused by manual adjustment in traditional mechanical devices, thus ensuring the accuracy of the post-forming circumference detection. In addition, using the gravity of the counterweight to drive the movement of the detection component simplifies the structure, reduces energy consumption, and improves the overall stability of the device.

[0018] Optionally, both the first guide and the second guide are rollers.

[0019] By adopting the above technical solution, the rollers, serving as both the first and second guide components, effectively reduce the frictional resistance of the flexible component during movement, thereby improving transmission efficiency and stability. Simultaneously, the roller design ensures smoother guidance of the flexible component, preventing jamming and ensuring precise and reliable movement of the detection component as it approaches or moves away from the clamping mechanism, further enhancing the accuracy of tire rear-shape circumference detection.

[0020] Optionally, the clamping mechanism includes a clamping drive, an upper clamp, and a lower clamp. The fixed end of the clamping drive is connected to the support mechanism. The upper clamp is connected to the telescopic end of the clamping drive. The lower clamp is connected to the support mechanism and is located below the upper clamp. The clamping drive is used to drive the upper clamp to move vertically, so that the upper clamp and the lower clamp clamp clamp the tire. The upper clamp is used to close the upper bead of the tire, and the lower clamp is used to close the lower bead of the tire.

[0021] By adopting the above technical solution, the clamping mechanism can achieve stable clamping of the tire. Specifically, the clamping drive component drives the upper clamping component to move vertically, cooperating with the lower clamping component to reliably fix the tire. Simultaneously, the upper and lower clamping components respectively seal the upper and lower bead openings of the tire, effectively preventing air leakage and ensuring the smooth progress of subsequent inflation and testing processes. This design eliminates human intervention, improves the automation and precision of operation, avoids errors caused by manual adjustments, and thus enhances the uniformity of the final product circumference.

[0022] Optionally, the pneumatic mechanism includes a pneumatic component and a connecting pipe, one end of which is connected to the pneumatic component, and the other end of which passes through the clamping mechanism and extends into the tire. The pneumatic component is electrically connected to the control component and is used to draw air or blow air into the connecting pipe.

[0023] By adopting the above technical solution, the pneumatic mechanism, through the cooperation of pneumatic components and connecting pipes, can achieve precise control of the gas inside the tire. One end of the connecting pipe is connected to the pneumatic component, and the other end passes through the clamping mechanism and extends into the tire, ensuring that gas can be accurately injected into or extracted from the tire, thereby realizing the tire inflation and deflation operations. This design effectively supports the circumference detection and control during the tire post-forming process, ensuring the circumference uniformity of the tire during the cooling and forming process, avoiding dimensional deviations caused by inaccurate gas control, and improving the product qualification rate.

[0024] Optionally, the measuring component includes a mounting bracket and a distance sensor. The mounting bracket is disposed on the support mechanism, and the distance sensor is disposed on the mounting bracket. The distance sensor is disposed on one side of the detection element, and the distance sensor is electrically connected to the control component.

[0025] By adopting the above technical solution, the distance sensor can accurately measure the horizontal distance between itself and the detection part, thereby accurately obtaining the position of the tire tread and acquiring the tire circumference data through the control component. The mounting bracket provides a stable mounting position for the distance sensor, ensuring the reliability and accuracy of the measurement process, avoiding errors caused by manual adjustment in traditional mechanical detection devices, and improving the automation and accuracy of post-determining circumference detection.

[0026] Optionally, the control mechanism includes a human-machine interface, which is electrically connected to the control component.

[0027] By adopting the above technical solutions, the human-machine interface allows operators to interact intuitively with the control components, enabling parameter setting, status monitoring, and result feedback for the tire rear circumference detection and control process. This improves the automation level of the device, reduces human intervention, lowers the difficulty of operation, and enhances the accuracy and efficiency of detection and control.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Through the cooperation of clamping mechanism and pneumatic mechanism, automatic tire inflation and gas extraction can be realized, ensuring that the tire is inflated and shaped while hot, effectively controlling the tire circumference, avoiding dimensional deviations caused by natural cooling, and improving product consistency.

[0030] 2. The testing organization uses the first and second drive components to drive the test piece to move precisely, and combines the measurement component to measure the horizontal distance in real time. There is no need for manual adjustment of the sensor position, which significantly improves the testing efficiency and accuracy, reduces human error, and lowers labor costs.

[0031] 3. The control mechanism automates the post-forming circumference detection and control by electrically connecting the measuring components and the pneumatic mechanism. It has a stable structure and is easy to operate, thus meeting the requirements for high efficiency and high precision. Attached Figure Description

[0050] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0052] like Figure 1As shown in the figure, this application discloses an automatic detection and control device for the rear shaping circumference of a tire (hereinafter referred to as the "device"). The device includes a support mechanism 1, a clamping mechanism 2, a pneumatic mechanism 3, a detection mechanism 4, and a control mechanism 5. It realizes the automatic detection of the rear shaping circumference of the tire 100, and can be conveniently applied to the circumference detection of tires 100 of different specifications, ensuring the uniformity of the shaping circumference of special tires 100, and making the circumference of the tire 100 conform to the tire detection circumference set by the vulcanization process formula.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, the support mechanism 1 provides a stable foundation for the entire device, ensuring that all components maintain precise positional relationships during operation. The clamping mechanism 2 is located on the support mechanism 1. The clamping mechanism 2 securely clamps the tire 100 and seals the upper and lower bezels of the tire 100, preventing gas leakage during tire inflation and ensuring the accuracy of the testing process. The pneumatic mechanism 3 is used to inflate or extract air from the tire 100, adjusting the tire circumference to match the set tire testing circumference.

[0054] After the tire 100 is clamped, its opening is closed, and it is connected to the pneumatic mechanism 3, the circumference of the tire 100 is detected by the detection mechanism 4. The detection mechanism 4 includes a first drive assembly, a second drive assembly, a detection element 43, and a measuring assembly. The first drive assembly and the second drive assembly are both located on the support mechanism 1. The detection element 43 is slidably connected to the support mechanism 1 and is located on one side of the clamping mechanism 2, where it abuts against the tread of the tire 100. Both the first drive assembly and the second drive assembly cooperate with the detection element 43. The second drive assembly is used to drive the detection element 43 to move towards the clamping mechanism 2, so that the detection element 43 abuts against the tread of the tire 100. The measuring assembly is located on the support mechanism 1 and on the side of the detection element 43 away from the clamping mechanism 2. The measuring assembly is used to measure the horizontal distance between itself and the detection element 43 in real time, so that the circumference of the tire 100 can be calculated. When the inspection is completed or the tire 100 needs to be replaced, the first drive assembly moves the inspection piece 43 away from the clamping mechanism 2 to reset it to its initial position away from the clamping mechanism 2, so as to perform the next inspection. The control mechanism 5 includes a control component 51, which is electrically connected to the measuring component and the pneumatic mechanism 3 to realize the automatic acquisition and processing of inspection data, and can automatically adjust the air pressure inside the tire 100 according to the inspection results to ensure that the circumference of the tire 100 meets the requirements. This device improves the automation of the movement of the inspection piece 43, eliminates the need for frequent manual adjustment of the measuring component, improves the stability of the measuring component, and thus ensures the accuracy of the measurement. The control mechanism 5, by electrically connecting the measuring component and the pneumatic mechanism 3, reduces human intervention, simplifies the operation steps, improves the inspection accuracy and efficiency, and reduces the defect rate.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, during testing, the second drive assembly moves the detection element 43 towards the clamping mechanism 2 until it contacts the tread of the tire 100. The measuring assembly then measures the horizontal distance between itself and the detection element 43, thus calculating the tire circumference. After measurement, the first drive assembly moves the detection element 43 away from the clamping mechanism 2 and returns it to its initial position to ensure the accuracy of the next measurement. Simultaneously, the control mechanism 5 controls the pneumatic mechanism 3 to inflate or deflate the tire 100 based on the measurement results, keeping the tire 100 within the process-controlled circumference range during the post-forming process. This ultimately achieves automatic detection and precise control of the tire circumference, improving production efficiency and product quality. Figure 1 and Figure 2 The diagram shows two states of the detection element 43: one is the initial position away from the tire 100, and the other is the state of contact with the tire 100; correspondingly, there are also two structures such as the detection mechanism 4.

[0056] like Figure 1 As shown, optionally, the clamping mechanism 2 includes a clamping drive member 21, an upper clamping member 22, and a lower clamping member 23. The clamping mechanism 2 can stably clamp the tire 100. The fixed end of the clamping drive member 21 is connected to the upper end of the support mechanism 1, and the telescopic end of the clamping drive member 21 extends and retracts in the vertical direction. The upper clamping member 22 is connected to the telescopic end of the clamping drive member 21, and the lower clamping member 23 is connected to the lower end of the support mechanism 1. The lower clamping member 23 is located below the upper clamping member 22. The clamping drive member 21 is used to drive the upper clamping member 22 to move vertically, cooperating with the lower clamping member 23, so that the upper clamping member 22 and the lower clamping member 23 clamp the tire 100, thereby achieving reliable fixation of the tire 100. After the clamping mechanism 2 clamps the tire 100, the upper clamping member 22 seals the upper opening of the tire 100, and the lower clamping member 23 seals the lower opening of the tire 100 to facilitate inflation of the tire 100, effectively preventing gas leakage and ensuring the smooth progress of the inflation and testing process. The clamping drive member 21 can be a cylinder, hydraulic cylinder, or electric telescopic rod, or other structure capable of extension and retraction. The shapes of the upper clamping member 22 and the lower clamping member 23 are not limited and can be set according to actual needs, as long as they can achieve sealing of the upper and lower openings of the tire 100 and stably clamp the tire 100.

[0057] like Figure 1As shown, optionally, the pneumatic mechanism 3 includes a pneumatic component 31 and a connecting pipe 32. Through the cooperation of the pneumatic component 31 and the connecting pipe 32, precise control of the gas inside the tire 100 is achieved. One end of the connecting pipe 32 is connected to the pneumatic component 31, and the other end of the connecting pipe 32 passes through the lower clamping member 23 and extends into the tire 100, ensuring that gas can be accurately injected into or extracted from the tire 100, thereby realizing the inflation and deflation operations of the tire 100. The pneumatic component 31 is electrically connected to the control component 51, and the pneumatic component 31 is used to draw air into or blow air into the connecting pipe 32. The pneumatic component 31 can be a structure capable of both drawing and blowing air, such as an air pump.

[0058] The pneumatic component 31 inflates or deflates the tire 100 through the connecting pipe 32, ensuring stable gas input and output, thereby effectively regulating the inflation volume inside the tire 100. This, in conjunction with the detection mechanism 4, completes the precise measurement and control of the tire 100 circumference, reducing errors caused by human intervention and improving the automation level and accuracy of the post-forming circumference detection.

[0059] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the measuring component includes a mounting bracket 441 and a distance sensor 442. The mounting bracket 441 is mounted on the support mechanism 1, and the distance sensor 442 is mounted on the mounting bracket 441. The distance sensor 442 is located on one side of the detection element 43 and is electrically connected to the control component 51. The type of distance sensor 442 is not limited and can be selected as needed. For example, it can be a laser sensor or an ultrasonic sensor. Depending on the operating conditions and accuracy requirements, various types of distance sensors 442 can be used. The control component 51 can be a PLC, which performs functions such as receiving and sending signals and data processing through its own functions.

[0060] Mounting bracket 441 provides a stable mounting position for distance sensor 442, ensuring reliability and accuracy during the measurement process. This reduces errors caused by manual adjustments in traditional mechanical inspection devices and improves the automation and accuracy of post-forming circumference inspection. The stably positioned distance sensor 442 can accurately measure the horizontal distance between itself and the inspection piece 43, thereby accurately obtaining the position of the tire 100 tread. The distance data is processed by the PLC to calculate the circumference data of the tire 100 and transmit it in real time. This allows the pneumatic mechanism 3 to control the internal pressure of the tire 100 in real time, achieving fully automatic detection and control of the post-forming circumference of the tire 100, thus helping to ensure the stability and uniformity of the circumference.

[0061] like Figure 1 , Figure 2 and Figure 4As shown, during the detection process, the detection component 43 first moves towards the clamping mechanism 2 under the drive of the second drive assembly until it abuts against the tread of the tire 100. At this time, the distance sensor 442 acquires the position information of the detection component 43 in real time and transmits the data to the control component 51. After the detection is completed, the second drive assembly drives the detection component 43 to reset. The entire process requires no manual intervention, ensuring the accuracy and stability of the measurement results, thereby effectively improving the automation and reliability of the tire 100 post-deformation circumference detection.

[0062] like Figure 1 , Figure 4 and Figure 5 As shown, optionally, the first driving assembly includes a slide rail 411, a slider 412, a moving drive member 413, and a toggle member 414. The slide rail 411 and the moving drive member 413 are both mounted on the support mechanism 1. The slider 412 is slidably connected to the slide rail 411. The toggle member 414 is connected to the moving end of the moving drive member 413, and the moving drive member 413 is used to drive the toggle member 414 to move. The toggle member 414 is located on one side of the slider 412 and is used to actuate the slider 412. A detection member 43 is mounted on the slider 412, enabling the moving drive member 413 to drive the detection member 43 to move away from the clamping mechanism 2. In this embodiment, the moving drive member 413 is located on one side of the slide rail 411, and the actuating member 414 is used to actuate the protrusion of the slider 412, which is located on the side of the detection member 43 near the clamping mechanism 2. This allows the actuating member 414 to push the slider 412 to move, thereby enabling the detection member 43 to move away from the clamping mechanism 2. The actuating member 414 can be a fork that abuts against the slider 412 to push the slider 412. The cooperation between the slide rail 411 and the slider 412 allows the detection member 43 to move horizontally stably, ensuring the accuracy of the detection process. The combined use of the moving drive member 413 and the actuating member 414 achieves precise control of the slider 412, so that when the tire 100 needs to be replaced, the detection member 43 can be reset and moved to the initial position through a mechanical structure.

[0063] The moving drive component 413 drives the actuating component 414 to move on the support mechanism 1. The actuating component 414 cooperates with the slider 412, thereby pushing the slider 412 to slide along the slide rail 411. Since the detection component 43 is set on the slider 412, the movement of the slider 412 can drive the detection component 43 to move away from the clamping mechanism 2, realizing precise adjustment of the position of the detection component 43. This design eliminates the need for manual adjustment, improves detection efficiency, reduces human error, and ensures the automation and reliability of tire circumference detection after 100mm.

[0064] like Figure 1 , Figure 4 and Figure 6As shown, optionally, the support mechanism 1 includes a gantry frame 11, a support frame 12, and a mounting plate 13. The gantry frame 11 is used to support the clamping mechanism 2. The lower end of the support frame 12 is connected to the bottom end of the gantry frame 11. The mounting plate 13 is located at the upper end of the support frame 12, and the slide rail 411 is located on the mounting plate 13. The moving drive component 413 is located at the upper end of the support frame 12 and on one side of the mounting plate 13, so that the actuating component 414 can cooperate with the slider 412.

[0065] like Figure 1 , Figure 4 and Figure 7 As shown, the support mechanism 1 consists of a gantry frame 11, a support frame 12, and a mounting plate 13, forming a stable structural foundation to ensure the operational reliability of the entire device. The gantry frame 11 is used to mount the clamping mechanism 2, ensuring the stable fixation of the tire 100 during the testing process.

[0066] like Figure 1 , Figure 4 and Figure 8 As shown, the cooperation between the support frame 12 and the mounting plate 13 provides an installation position for the slide rail 411 and the moving drive component 413, enabling the first drive component to accurately drive the detection component 43 to move, thereby achieving accurate contact and measurement of the tire tread of the tire 100.

[0067] Optionally, the moving drive component 413 is a rodless cylinder, which enables precise linear motion control, ensuring that the detection component 43 moves smoothly as it approaches or moves away from the clamping mechanism 2. The rodless cylinder design eliminates the structural limitations of traditional cylinder piston rods, resulting in higher space utilization and improved system compactness and stability. Furthermore, the rodless cylinder offers high response speed and positioning accuracy, contributing to improved detection efficiency and accuracy of results, thus better meeting the precision and automation requirements of the tire 100mm rear-circumference automatic detection and control device.

[0068] like Figure 1 , Figure 2 and Figure 4As shown, optionally, the second drive assembly includes a counterweight 421, a flexible member 422, a first guide member 423, and a second guide member 424. The first guide member 423 is disposed on the gantry 11, and the second guide member 424 is disposed on the mounting plate 13. The first guide member 423 and the second guide member 424 are horizontally distributed. The counterweight 421 is connected to the first end of the flexible member 422, and the second end of the flexible member 422 is connected to the slider 412. The flexible member 422 is sequentially wound around the first guide member 423 and the second guide member 424, so that the vertical downward movement of the counterweight 421 drives the slider 412 to move horizontally towards the clamping mechanism 2 until the detection member 43 connected to the slider 412 abuts against the tread of the tire 100. When the second drive assembly needs to move the detection member 43, the slider 412 can be moved to the end of the slide rail 411 near the clamping mechanism 2 to avoid interference and ensure that the detection member 43 can reliably abut against the tread of the tire 100. The counterweight 421 can be a weight; the flexible component 422 can be a steel wire rope. It is understood that the driving form of the detection component 43 is not limited to a rodless cylinder; a cylinder can be used to achieve the action. Furthermore, under the pneumatic control design, the forward and backward movement of the detection component 43 can be completely controlled by the cylinder. That is, the second driving component can be another fork set on the moving driving component 413, used to push the detection component 43 to move towards the clamping mechanism 2.

[0069] The cooperation between the counterweight 421 and the flexible component 422 enables the automatic and reliable contact of the detection component 43 with the tire 100 tread, ensuring the accuracy of the measurement by the detection component 43 and improving detection efficiency and precision. The horizontal distribution design of the first guide component 423 and the second guide component 424 makes the transmission of the flexible component 422 more stable and reliable, avoiding errors caused by manual adjustment in traditional mechanical devices, thereby ensuring the accuracy of the post-forming circumference detection. In addition, using the gravity of the counterweight 421 to drive the movement of the detection component 43 simplifies the structure, reduces energy consumption, and improves the overall stability of the device. In use, when the counterweight 421 moves vertically downward under its own weight, it can drive the flexible component 422 to successively pass around the first guide component 423 and the second guide component 424, thereby pulling the slider 412 to move horizontally towards the clamping mechanism 2. At this time, the position of the weight is... Figure 2 The weight is positioned below, and the detection element 43 abuts against the tread of the tire 100. This design allows the detection element 43 to accurately abut against the tread of the tire 100, completing the initial positioning action for circumference detection. After the detection is completed, the first drive assembly overcomes the gravity of the weight, driving the counterweight 421 to move upwards. Figure 2 The weight is positioned at the top, and the entire process requires no human intervention, improving detection efficiency and accuracy.

[0070] like Figure 1 , Figure 2 and Figure 4As shown, optionally, both the first guide member 423 and the second guide member 424 are rollers. The rollers rotatably connected to the support mechanism 1, serving as the first guide member 423 and the second guide member 424, effectively reduce the frictional resistance of the flexible member 422 during movement, improving transmission efficiency and stability. Simultaneously, the roller design makes the guidance of the flexible member 422 smoother, avoiding jamming, thereby ensuring that the detection member 43 moves accurately and reliably as it approaches or moves away from the clamping mechanism 2, further improving the accuracy of the tire 100 post-forming circumference detection.

[0071] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the control mechanism 5 includes a human-machine interface 52, which is electrically connected to the control component 51. The human-machine interface 52 allows operators to interact intuitively with the control component 51, enabling parameter setting, status monitoring, and result feedback for the tire 100 post-deformation circumference detection and control process. This improves the automation level of the device, reduces human intervention, lowers the difficulty of operation, and enhances the accuracy and efficiency of detection and control.

[0072] During testing, the circumference of the standard tire 100 is set on the HMI (Human-Machine Interface) 52, and the upper and lower floating tolerances are set. Data is then communicated to the PLC. After vulcanization, the tire 100 is automatically picked up by a robotic arm and placed on the lower clamping member 23. The lower clamping member 23 is sealed to the lower end of the tire. The upper clamping member 22 is driven downward by the clamping drive member 21 and presses down to contact and seal with the upper end of the tire 100, thus achieving the limitation and sealing of the tire 100.

[0073] like Figure 1 , Figure 2 and Figure 4As shown, both the clamping mechanism 2 and the detection mechanism 4 can communicate with the control component. After the tire 100 is placed in position, the second drive component drives the detection component 43 forward to contact the tire 100 tread. The connecting pipe 32 communicates with the inside of the tire 100 through the lower clamping component 23 to inflate the tire 100. Inflating the tire 100 will push the detection component 43 backward. During the shaping process, the distance sensor 442 monitors the position of the detection component 43 in contact with the tire 100 tread and transmits the data to the PLC for calculation, controlling the pneumatic mechanism 3 to adjust the air pressure inside the tire 100, ultimately ensuring the uniformity of the tire 100's circumference. The data detected by the ranging sensor 442 on the detection element 43 is communicated to the PLC. The PLC receives the data and compares it with the data set on the human-machine interface 52. Through the comparison of the data set on the human-machine interface 52, the PLC transmits the signal to the pneumatic mechanism 3. The pneumatic mechanism 3 controls the air pressure inside the tire 100 through instructions, performing inflation and deflation actions to maintain the stability of the outer circumference of the tire 100. The process is fully automatic. Since the clamping mechanism 2 can fix the axis position of the tire 100, and the measuring component is fixed on one side of the clamping mechanism 2, the distance between the measuring component and the axis of the tire 100 is fixed. By detecting the horizontal distance between the measuring component and the detection element 43, the horizontal distance between the detection element 43 and the axis of the tire 100 can be obtained, which is the diameter of the tire 100. Therefore, the circumference of the tire 100 can be obtained from the diameter of the tire 100.

[0074] Understandably, the device also includes necessary structures for connection, support, drive, positioning, limiting, sealing and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0075] The implementation principle of the automatic tire circumference detection and control device according to the embodiments of this application is as follows: the support mechanism 1 provides a stable foundation for the entire device; the clamping mechanism 2 can firmly clamp the tire 100 and simultaneously close the upper and lower openings of the tire 100; the pneumatic mechanism 3 realizes the inflation and deflation operations of the tire 100, ensuring real-time adjustment of the tire pressure during the detection process; the second drive component in the detection mechanism 4 enables the detection element 43 to accurately abut against the tire 100 tread; the measuring component acquires the horizontal distance between the detection element 43 abutting against the tire 100 and itself in real time, thereby obtaining the circumference of the tire 100; the control mechanism 5 realizes automatic acquisition and processing of detection data through electrical connection between the measuring component and the pneumatic mechanism 3, and automatically adjusts the tire pressure inside the tire 100 according to the detection results, thus completing the reliable detection of the tire circumference; the first drive component enables the detection element 43 to be reset so that the tire 100 can be replaced, improving the automation level of the movement of the detection element 43 and eliminating the need for frequent adjustment of the measuring component. The overall solution reduces human intervention, simplifies operation procedures, improves detection accuracy and efficiency, and reduces the defect rate.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
