Description

Technical Field

[0001] This utility model relates to the field of film thickness measurement technology, specifically to a film thickness measurement device. Background Technology

[0002] In modern industrial production and quality control, measuring the film thickness on pipes and other metal surfaces is a crucial step in ensuring product quality, service life, and functional performance. Especially in the production and processing of stainless steel pipes, it is often necessary to apply anti-corrosion coatings, insulating layers, conductive coatings, or other functional films to the pipe surface. The uniformity of these film thicknesses directly affects the pipe's corrosion resistance, conductivity, mechanical properties, and aesthetics under different environments. To ensure that these coatings meet design standards, film thickness measurement becomes a critical quality inspection step. Currently, commonly used film thickness measurement methods include magnetic thickness measurement, eddy current thickness measurement, laser interferometry, and ultrasonic thickness measurement. These methods each have advantages in different scenarios, but they also have certain limitations in practical applications.

[0003] Traditional film thickness measurement equipment often employs a split structure, meaning the cable, probe, and main unit are separate. During use, these components require frequent plugging and unplugging and reconnection of interfaces. Each operation is not only time-consuming and labor-intensive but also prone to loosening of data interfaces and insecure connections, affecting signal transmission stability and leading to measurement data deviations or errors. Furthermore, due to frequent plugging and unplugging, wear and tear on the data interface and cable contact points becomes increasingly severe, significantly reducing the equipment's reliability and accuracy over long-term use. In addition, this structural design presents inconveniences during storage and transportation; the cable is prone to tangling, and the probe lacks effective protection when not in use, greatly shortening the equipment's lifespan.

The housing 1 serves as the support and protection structure for the entire device, bearing all parts, preventing damage to the internal structure from the external environment, and providing a stable operating platform. The winding post 2 is used to store and fix the connecting cable 5. When the device is not in use, the cable can be wound around the winding post to reduce cable pulling and wear. The baffle 3 provides limiting protection for the wound cable to prevent the cable from loosening or slipping. The sealing joint 4 ensures the sealing between the connecting cable and the housing, effectively preventing dust, moisture or other impurities from entering the device, ensuring the stability and durability of the cable connection. The connecting cable 5 serves as a signal and power transmission channel, transmitting data and power from the housing to the handheld part and the ultrasonic probe, ensuring stable and reliable signal transmission. The handheld part 6 provides a stable gripping platform for the operator.

[0023] A protective sleeve 7 is fixedly installed at the bottom of the housing 1, a switch 8 is fixedly installed at the top of the handheld part 6, and an ultrasonic probe 9 is fixedly installed at the end of the handheld part 6 away from the connecting cable 5. The switch 8 serves as the start and stop control device of the device. The operator controls the working status of the entire device by pressing the switch. The ultrasonic probe 9 is responsible for emitting and receiving ultrasonic signals. The membrane thickness is calculated by measuring the propagation time and reflection of the sound waves in the membrane layer. The protective sleeve 7 protects the ultrasonic probe when the device is not in use, preventing the probe from being physically damaged or contaminated during storage and transportation.

[0024] A digital display screen 10 is fixedly installed at the upper end of the housing 1, a data interface 11 is fixedly installed at the right end of the housing 1, a control button 12 is fixedly installed at the upper end of the housing 1, a speaker 13 is fixedly installed behind the control button 12, a battery 14 is fixedly installed inside the housing 1, and a measuring device body 15 is fixedly installed inside the housing 1. The digital display screen 10 is used to display measurement data, equipment status, and operation information in real time, providing clear and intuitive measurement results. The data interface 11 is used to transmit the measured data to an external storage device or computer for storage and analysis, providing a data transmission channel.

[0025] Working Principle: Before use, the housing 1 serves as an overall support and protective structure, tightly integrating all components to provide a stable operating platform. The operator first firmly grips the handheld unit 6 and removes the ultrasonic probe 9 from the protective sleeve 7, ensuring that the connecting cable 5 is unwound from the winding post 2. The winding post 2 is used to wind and store the cable when the equipment is not in use. The baffle 3 provides limiting protection for the wound cable, preventing it from slipping or becoming tangled. First, apply coupling agent to the object surface, then align the ultrasonic probe 9 with the surface of the stainless steel tube to be measured. Press the switch 8 on the handheld unit 6 to power on the device and put it into working condition. The main body 15 of the measuring device starts working, controlling the ultrasonic probe 9 to emit ultrasonic signals. After the signals are reflected back to the probe from the stainless steel tube membrane, the main body 15 receives and processes the data, calculating the membrane thickness. The results are displayed in real time on the digital display screen 10, allowing the operator to directly read the data. If data needs to be transmitted to external devices, the operator can export the measurement data through the data interface 11 for further storage or analysis. Throughout the measurement process, the sealing joint 4 ensures a tight connection between the connecting cable 5 and the housing 1, preventing external dust or moisture from entering the device. The control button 12 can be used to adjust the measurement parameters or functions of the equipment. The speaker 13 emits a prompt tone upon completion of the measurement, reminding the operator that the measurement is complete or that an equipment malfunction has occurred. After the measurement is completed, the operator turns off the switch 8 and places the ultrasonic probe 9 back into the protective sleeve 7 to prevent damage to the probe during storage. Subsequently, the connecting cable 5 is wound sequentially onto the winding post 2. After winding, the baffle 3 limits the cable to prevent it from becoming tangled or falling off. After all components are stored, the equipment remains in a complete, integrated state, facilitating storage and future use.
