Description

Technical Field

[0001] This utility model belongs to the field of finished product quality inspection of all-steel or engineering tires, specifically relating to a handheld contact wireless device for measuring the thickness of the inner wall rubber sheet of a tire. Background Technology

[0002] The tire inner wall rubber, also known as the inner liner, is a crucial part of tire design. Its thickness directly affects the tire's puncture resistance, durability, and safety. Especially now, to reduce material costs, tire factories use pre-vulcanization of the rubber, resulting in even thinner inner liner rubber. During production, this inevitably leads to the tire inner wall, particularly the shoulder rubber, falling below the minimum thickness limit. This poses a significant safety hazard. Normally, only exposed steel wires are visible to the naked eye; otherwise, they cannot be detected manually or measured with data. Tire defects pose a serious threat to vehicle safety.

[0003] Currently, traditional tire inner wall liner thickness testing mainly relies on experienced workers visually inspecting for exposed steel wires and manually checking for any impending exposure. Factories that prioritize quality purchase offline measuring instruments, where manual handheld depth gauges are used to perform contact measurements on areas prone to thinning during production. Measurements are taken at three or six points on the tire shoulder and sidewall; local compliance indicates overall tire compliance. The controller and thickness probe are connected by a cable, but due to the limited cable length, the main unit needs to be moved after each tire measurement, which cannot meet customers' requirements for portability, real-time communication, and high-efficiency measurement.

[0004] The main purpose of this invention is to provide a handheld contact wireless device for measuring the thickness of tire inner wall film, so as to solve the problem of the measurement range being limited by cables in the existing measurement operation, and thus help to improve work efficiency.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a handheld contact wireless measuring device for the thickness of tire inner wall film, comprising a handheld contact wireless probe and a control host;

[0006] The handheld contact wireless probe is used to measure the thickness of the inner wall film of a tire;

[0007] The handheld contact wireless probe is wirelessly connected to the control host.

[0008] The control host is used to receive, process, and store measurement data from the handheld contact wireless probe.

[0009] Preferably, this invention also includes a Management Execution System (MES), which is used to analyze and store the measurement data collected by the control host for extended periods. Upon completion of work or a phase of measurement, the control host uploads data in batches to the MES for analysis and long-term storage.

[0020] In a preferred embodiment of this invention, the control host includes a touch screen input / output unit, a wireless receiving module, a signal processing unit, and a battery management system;

[0021] The touchscreen input / output unit is used to manage formula settings, select calibration tasks, and display status. Different types of tires require different measurement standards. By setting different measurement standard formulas or different calibration tasks for different types of tires, different types of tires can be tested.

[0022] The wireless receiving module is used to receive signals from the wireless transmission module;

[0023] The signal processing unit is used to analyze and process the signals received by the wireless receiving module;

[0024] The battery management system manages the battery status and displays it on the touch screen input / output unit, allowing operators to charge the equipment in a timely manner and avoid affecting measurement operations.

[0025] Preferably, the measuring end of the handheld contact wireless probe is detachably equipped with a wear-resistant protective cap. Since it uses contact measurement, the measuring end of the handheld contact wireless probe is prone to wear. Therefore, a wear-resistant protective cap is provided on the measuring end of the handheld contact wireless probe to prevent wear. Furthermore, the protective cap can be quickly replaced after wear.

[0026] Preferably, the handheld measuring module of this invention is equipped with a barcode scanner, and the signal from the barcode scanner is transmitted synchronously with the measurement data from the handheld contact wireless probe. By setting up the barcode scanner and transmitting its signal synchronously with the measurement data from the handheld contact wireless probe, the information for each tire can be matched one-to-one, facilitating customer quality tracking and improving quality control.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: The handheld contact wireless measuring device for tire inner wall film thickness includes a handheld contact wireless probe and a control host. The handheld contact wireless probe is used to measure the thickness of the tire inner wall film. Since the handheld contact wireless probe is wirelessly connected to the control host, the measured data can be transmitted to the control host in real time for storage and processing.

[0039] The handheld contact wireless probe 1 is used to measure the thickness of the inner wall film of a tire. The handheld contact wireless probe 1 is designed in a handheld shape, making it lightweight and easy to hold.

[0040] The handheld contact wireless probe 1 is wirelessly connected to the control host 2. The control host 2 is placed in an area where wireless reception is possible, and the handheld contact wireless probe 1 and the control host 2 engage in real-time wireless interactive communication.

[0041] The control host 2 is used to receive, process, and save the measurement data from the handheld contact wireless probe 1. The control host 2 sets multiple recipes, selects one, and downloads it to the handheld contact wireless probe 1. The operator holds the handheld contact wireless probe 1, inserts it into the tire, and applies appropriate pressure to the tire's measurement area. Measurements can be taken multiple times, and the downloaded recipes set by the control host 2 are compared. After the measurement data is confirmed, it is uploaded to the control host 2 and saved according to the measurement location. After the work is completed or a phase of measurement is finished, the data from the control host 2 is uploaded in batches to the MES system 3 for analysis and long-term storage. The recipes here represent measurement standards and requirements for different tires or different locations.

[0042] like Figure 1 As shown, the handheld contact wireless device for measuring the thickness of tire inner wall film also includes a MES system 3, which is used to analyze and store the measurement data collected by the control host 2 for a long time.

[0043] like Figure 2 As shown, the handheld contact wireless probe 1 includes a handheld measurement module 11 and a signal processing module 12 that are electrically connected to each other.

[0044] The handheld measurement module 11 includes a thickness measurement sensor 111. Specifically, the thickness measurement sensor 111 is a magnetic sensor. Under hand pressure, the magnetic sensor contacts the film being measured and emits a magnetic signal that detects a metal object inside the tire. Different distances between the magnetic sensor and the metal object result in different induced currents. This minute change in current converts the thickness distance information into a linearly changing current signal. The size and detection range of the thickness measurement sensor 111 vary depending on the type of tire being tested. For all-steel radial tires, it is equipped with an 11mm probe diameter and a detection range of 0-5mm.

[0045] The signal processing module 12 includes a wireless transmission module 121. The wireless transmission module 121 is used to transmit the data measured by the thickness measurement sensor 111 to the control host 2.

[0046] The handheld measurement module 11 and the signal processing module 12 share the same housing.

[0047] The handheld measurement module 11 also includes a light 112 and multiple status indicator lights 113 that face the same direction as the thickness measurement sensor 111.

[0048] The status indicator light 113 is used to indicate the measurement status. Multiple status indicator lights 113 are provided, specifically including a pass light, a fail light, a measurement count light, and a confirmation light, to provide status indications according to customer needs.

[0049] Specifically, the illumination lamp 112 is one or more LED lamps, and multiple LED lamps can be arranged circumferentially around the thickness measurement sensor 111. The handheld contact wireless probe 1 is also equipped with a data acquisition button and an LED lamp control button.

[0050] The signal processing module 12 also includes a battery 122 and a display screen 123.

[0051] The battery 122 is used for power supply.

[0052] The display screen 123 is used to display the measurement data returned by the control host 2, the parameter information and working status of the handheld contact wireless probe 1.

[0053] The control host 2 adopts an embedded system design, which is convenient for portability and can also be expanded to processing units such as computers. Figure 3 As shown, the control host 2 includes a touch screen input / output unit 21, a wireless receiving module 22, a signal processing unit 23, and a battery management system 24.

[0054] The touchscreen input / output unit 21 is used to manage recipe settings, select calibration tasks, and display status.

[0055] The wireless receiving module 22 is used to receive signals from the wireless transmission module 121.

[0056] The signal processing unit 23 is used to analyze and process the signals received by the wireless receiving module 22. Specific analysis and processing methods are not within the scope of this application and will not be elaborated upon here.

[0057] The battery management system 24 manages the battery status and displays it on the touch screen input / output unit 21.

[0058] The control host 2 stores data and transmits it to the host MES system 3 via network or USB for unified analysis. The control host 2 also has an audio prompt function.

[0059] The measuring end of the handheld contact wireless probe 1 is detachably equipped with a wear-resistant protective cap. Specifically, the protective cap is located at the end of the thickness measuring sensor 111.

[0060] The handheld measurement module 11 is equipped with a barcode scanner (not shown in the figure). The signal from the barcode scanner is transmitted synchronously with the measurement data from the handheld contact wireless probe 1, and the scanned information is also transmitted to the control host 2.

[0061] In this embodiment, the control host 2 has the following functions:

[0062] 1. It has wired network, WiFi, wireless, USB, and barcode scanner functions.

[0063] 2. Receive measurement data sent by the wireless transmission module 121, calculate and display the measurement value, and save it to the internal storage card;

[0064] 3. Save the data and transmit it to the host computer MES system via network or USB, where the host computer will perform unified analysis.

[0065] Example 2

[0066] The difference from Embodiment 1 is that the handheld measurement module 11 and the signal processing module 12 are set separately, and the handheld measurement module 11 and the signal processing module 12 are connected by a wire harness.

[0067] In this embodiment, by separating the handheld measurement module 11 and the signal processing module 12, the heavier battery 122 and the larger display screen 123 are both placed on the signal processing module 12, which helps to reduce the weight and size of the handheld measurement module 11 and is more conducive to handheld measurement. For convenient carrying, a special waist bag or other device can be set up to hold the signal processing module 12.

[0068] Alternatively, the signal processing module 12 can be configured as a ring structure and worn on the wrist for easier measurement.
