Description

Technical Field

[0001] This invention relates to the field of tire bead technology, specifically to a tire bead front and back detector and detection method. Background Technology

[0002] Currently, the inspection of the front and back of tire steel wire rings is mainly carried out manually, with upstream equipment ensuring the process meets the needs of tire factories for inspecting tire steel wire rings. However, the drawback is that the process involves human movement and placement, which can easily lead to the steel wire rings being placed backwards, resulting in low overall tire scrapping and product pass rates, causing losses to the factory. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to avoid the tire steel wire ring being placed in reverse. To solve the above problem, a tire steel wire ring orientation detection instrument is provided.

[0004] The object of this invention is achieved in the following manner:

[0005] A tire wire bead forward / reverse detection instrument, the instrument includes an MCU, a magnetic sensor array, and a linear amplifier, wherein the probe signal on the magnetic sensor array is sent to the MCU through the linear amplifier.

[0006] The magnetic sensor array includes multiple magnetic sensors arranged in the same plane.

[0007] The MCU is also connected to an alarm display system.

[0008] The alarm display system includes an alarm light, which is composed of two light sources and has the function of distinguishing different results, and has the function of emitting red light or green light.

[0009] The detector also includes a 24V switching power supply circuit, which supplies power to the MCU, linear amplifier, and magnetic sensor array.

[0010] The detector includes a housing, and the MCU, magnetic sensor array, and linear amplifier are all housed inside the housing. The probes of the magnetic sensor array are arranged in a row on one side of the housing.

[0011] The MCU communicates with the host computer via a built-in Bluetooth module.

[0012] A detection method using the aforementioned tire bead front / back detector, the method comprising:

[0013] Align the probe of the magnetic sensor array in the detector with the wire loop;

[0014] Each magnetic sensor in the magnetic sensor array acquires data signals from the steel wire coil below it, resulting in a voltage sequence data.

[0015] The wire coil data is amplified by a linear amplifier and then converted into a digital signal by the ADC built into the MCU.

[0016] The digital signal is filtered and compared with the data pre-stored in the MCU calibration library to obtain the detection result.

[0017] The data pre-stored in the MCU calibration library includes voltage sequences measured by the magnetic sensor array when the wire coil is placed normally and in reverse. When placed normally, the distance between the magnetic sensor and the wire coil gradually decreases from left to right, and the measured voltage gradually increases. When placed in reverse, the distance between the magnetic sensor and the wire coil gradually increases from left to right, and the measured voltage gradually decreases.

[0018] When the detection result indicates that the device is placed normally, the MCU outputs a signal to control the green light in the alarm display circuit to illuminate; when the detection result indicates that the device is placed in reverse, the MCU outputs a signal to control the red light in the alarm display circuit to illuminate.

[0019] The beneficial effects of this invention are: This invention is safe and reliable, achieves accurate detection, and the use of MCU and sensors ensures the precise execution of the entire working process and real-time detection of tire rims. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same technical meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The wire bead in this invention is a rigid ring made of rubber-coated steel wires arranged in a specific cross-sectional shape. Its function is to impart the necessary strength and rigidity to the tire bead, ensuring that the tire is firmly secured to the rim.

[0029] like Figure 1 As shown, a tire wire bead forward and reverse detection instrument is disclosed. The instrument includes an MCU, a magnetic sensor array, and a linear amplifier. The probe signal on the magnetic sensor array is sent to the MCU through the linear amplifier.

[0030] The magnetic sensor array includes multiple magnetic sensors arranged in the same plane.

[0031] Preferably, this invention employs six magnetic sensors, each of which is connected to the MCU via a linear amplifier.

[0032] The MCU is also connected to an alarm display system.

[0033] The alarm display system includes an alarm light, which is composed of two light sources and has the function of distinguishing different results, and has the function of emitting red light or green light.

[0034] The detector also includes a 24V switching power supply circuit, which supplies power to the MCU, linear amplifier, and magnetic sensor array.

[0035] The detector includes a housing, and the MCU, magnetic sensor array, and linear amplifier are all housed inside the housing. The probes of the magnetic sensor array are arranged in a row on one side of the housing.

[0036] The MCU communicates with the host computer via a built-in Bluetooth module.

[0037] A detection method using the aforementioned tire bead front / back detector, the method comprising:

[0038] Align the probe of the magnetic sensor array in the detector with the wire loop;

[0039] Each magnetic sensor in the magnetic sensor array acquires data signals from the steel wire coil below it, resulting in a voltage sequence data.

[0040] The wire coil data is amplified by a linear amplifier and then converted into a digital signal by the ADC built into the MCU.

[0041] The digital signal is filtered and compared with the data pre-stored in the MCU calibration library to obtain the detection result.

[0042] The data pre-stored in the MCU calibration library includes voltage sequences measured by the magnetic sensor array when the wire coil is placed normally and in reverse. When placed normally, the distance between the magnetic sensor and the wire coil gradually decreases from left to right, and the measured voltage gradually increases. When placed in reverse, the distance between the magnetic sensor and the wire coil gradually increases from left to right, and the measured voltage gradually decreases.

[0043] When the detection result indicates that the device is placed normally, the MCU outputs a signal to control the green light in the alarm display circuit to illuminate; when the detection result indicates that the device is placed in reverse, the MCU outputs a signal to control the red light in the alarm display circuit to illuminate.

[0044] like Figure 3 and Figure 4 As shown, the detector includes a housing, and the MCU, magnetic sensor array, and linear amplifier are all housed inside the housing. The probes of the magnetic sensor array are arranged in a row on one side of the housing.

[0045] like Figure 2 As shown, before use, a 24V switching power supply circuit powers the Bluetooth chip, high-precision linear amplifier, magnetic sensors, and alarm display system. Then, each module is initialized. In use, the six magnetic sensors collect data signals from the steel wire coil. After the high-precision linear amplifier amplifies the signal, the resulting signal is converted into a digital signal by the MCU's built-in ADC. After multiple data samplings, the data is filtered. The final filtered data is compared with pre-stored data in the MCU's calibration library to obtain the detection result. The detection result indicates that when the steel wire coil is properly positioned, the MCU controls the alarm display system to illuminate a green light; otherwise, a red light illuminates.

[0046] The host computer calibration library pre-stores voltage sequences measured by six magnetic sensors when the wire coil is placed normally and in reverse. For example, when placed normally... Figure 5 As shown in the diagram (where 1-6 represent magnetic sensors, and the circles below the magnetic sensors represent the steel wires inside the wire coil), the distance between the six magnetic sensors and the wire coil gradually decreases from left to right, and the measured voltage gradually increases. Figure 6 As shown, when placed in reverse, the distance between the six magnetic sensors and the wire loop gradually increases from left to right, and the measured voltage gradually decreases.

[0047] Overall, this invention is safe and reliable, achieving accurate detection. The use of MCU and sensors ensures precise execution of the entire working process, real-time detection of tire rims, and monitoring through data transmission to a host computer.

[0048] In summary, this invention is simple to operate, safe and reliable, and achieves accurate detection. The use of MCU and sensors ensures the precise execution of the entire working process and enables real-time detection of tire rims.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be considered within the scope of protection of the present invention.
