Description

Technical Field

[0001] This utility model relates to the field of thickness measuring device technology, and in particular to a dual-laser synchronous thickness measuring device. Background Technology

[0002] Traditional single-laser thickness measurement methods are susceptible to factors such as surface roughness and light reflectivity, resulting in inaccurate thickness measurements, especially with highly reflective or low-reflective materials. Contact-based thickness measurement methods inevitably damage the surface of the object being measured and struggle to meet the demands of real-time online measurement, limiting their application in industrial production. Existing equipment exhibits poor stability in complex environments (such as vibration, high temperatures, or dust), affecting the reliability of measurement results. Therefore, there is an urgent need for a thickness measurement technology that can improve measurement accuracy, enable non-contact operation, and is suitable for online use, meeting the requirements of efficient and precise inspection in modern industry. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-laser synchronous thickness measurement device.

[0005] A dual-laser synchronous thickness measurement device includes a main body, a base fixedly installed at the bottom of the main body, a measurement platform and a detection component inside the main body, and adjustment brackets connected and installed on both sides of the measurement platform and the detection component inside the main body. A guide rail device is provided on the measurement platform. The detection component includes laser emitting modules A and B, laser receiving modules A and B, and a signal processing unit.

[0006] Preferably, the base is made of marble.

[0007] Preferably, the surface of the measuring platform is covered with an anti-slip coating.

[0009] Preferably, the signal processing unit is interfaced with the industrial control system.

[0010] The beneficial effects of this utility model are:

[0011] This invention eliminates errors caused by differences in surface roughness and reflectivity due to single-laser synchronous measurement technology, improving the accuracy of thickness measurement, and is particularly suitable for materials with complex surface properties. It avoids damage to the surface of the object being measured, while adapting to the needs of online real-time thickness detection, significantly improving production efficiency and equipment lifespan. Based on the low thermal expansion and vibration resistance of the marble base, the equipment can maintain stable operation even in high-temperature, vibration, and complex production environments, making it widely applicable. The equipment is suitable for thickness detection of metals, non-metals, and composite materials, meeting the high-precision thickness measurement needs of various industries and possessing high industrial application value. Furthermore, the device has a compact design, occupies little space, and is easy to install and maintain, meeting the convenience requirements for use in industrial settings.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: Refer to Figure 1-4 The dual-laser synchronous thickness measurement device includes a main body 1, a base 2 fixedly installed at the bottom of the main body 1, a measuring platform 3 and a detection component 4 inside the main body 1, and an adjustment bracket 5 connected and installed on both sides of the measuring platform 3 and the detection component 4 inside the main body 1. A guide rail device is installed on the measuring platform 3. The detection component 4 includes laser emitting modules A and B, laser receiving modules A and B, and a signal processing unit.

[0019] Furthermore, the base 2 is made of marble.

[0020] Furthermore, the surface of the measuring platform 3 is covered with an anti-slip coating.

[0021] Furthermore, laser emitting modules A and B are installed on the upper and lower sides, respectively.

[0022] Furthermore, the signal processing unit interfaces with the industrial control system.

[0023] Working principle: Laser emitting modules A and B are installed on the upper and lower sides of the object, respectively, to emit precisely calibrated parallel laser beams. Laser receiving modules A and B receive or transmit the laser signals and transmit them to the signal processing unit.

[0024] The signal processing unit is the core component of the system. It measures the thickness of the object under test in real time by accurately calculating the time difference and optical path offset of laser propagation. It also supports data storage and interface output functions and can be connected to the industrial control system. The adjustment bracket 5 is used to fix and adjust the angle and position of the laser emitting module and the receiving module to adapt to the objects under test of different sizes and shapes.

[0025] The measurement platform 3 is used to place the object to be measured. Its surface is covered with an anti-slip coating or a guide rail device to ensure the stability and accurate positioning of the object during the measurement process. In practical applications, the laser acts synchronously on the upper and lower surfaces of the object. The receiving module collects and transmits the signals to the processing unit, which analyzes the differences in the optical path in real time and calculates the thickness of the object, thereby achieving high-precision, non-contact, real-time measurement.
