Therefore, rapid, accurate, and comprehensive online or offline detection of material thickness is crucial during production and processing. However, existing thickness measurement technologies and devices have many limitations in practical applications, severely restricting the accurate control of product quality and the improvement of production efficiency. Traditional measurement methods (such as micrometers) can only measure material thickness within a small area, failing to obtain thickness measurements in multiple regions of the material. This necessitates frequent clamping of the material at different locations for measurement, reducing measurement efficiency. Utility Model Content

[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0020] like Figure 1 - Figure 3 As shown, this utility model provides a thickness measuring device.

[0021] In an exemplary embodiment, the thickness measuring device includes a base 1, a driving mechanism, a placement mechanism, and a detection mechanism. The base 1 is equipped with a driving mechanism for driving the placement mechanism to move horizontally. The placement mechanism includes a fixed plate 4, a driver 3, and a detection plate 6. The driver 3 is mounted on the fixed plate 4, and the detection plate 6 is located at the output end of the driver 3. The driver 3 drives the detection plate 6 to rotate, and the detection plate 6 has a set of detection holes. The detection mechanism is mounted on the base 1, and the detection end of the detection mechanism corresponds to the set of detection holes.

[0022] In this embodiment, the horizontal movement of the placement mechanism is achieved through a drive mechanism, and the rotation of the detection plate 6 is achieved through a driver 3, enabling the detection hole group to perform measurements at multiple positions and angles. The detection mechanism, in cooperation with the detection hole group, achieves multi-point detection of material thickness. Compared to traditional fixed measuring devices, this solution can complete multi-position, multi-angle thickness measurements without moving the material being measured, effectively improving measurement efficiency and data comprehensiveness. Specifically, the horizontal movement mechanism expands the measurement range, the rotation mechanism increases the measurement angle, and measurement is achieved along the material's axial direction, thus improving measurement efficiency.

[0023] In an exemplary embodiment, the detection hole group includes a first detection hole 601 and a second detection hole 602. The first detection hole 601 extends along the moving direction of the placement mechanism, and the second detection hole 602 is provided in multiple circumferentially spaced along the rotation center of the detection plate 6.

[0024] In this embodiment, by integrating linear and rotary detection holes onto the same detection plate 6, continuous thickness detection of the linear region of the material is achieved through the horizontal movement of the placement mechanism. Simultaneously, the driver 3 rotates the detection plate 6 to switch between different angles of the second detection holes 602, enabling multi-angle thickness measurement. The extended design of the first detection hole 601 avoids the problem of repeated start-stop operations required by traditional point-based measurements, while the circumferential distribution of the second detection holes 602 allows for multi-angle measurements to be completed in a single clamping operation. Therefore, the detection hole group used in this application reduces the number of times the detection position needs to be adjusted, eliminates measurement errors caused by changing detection tools, and combines the linear movement detection and rotation angle detection processes into a synchronous action, effectively improving the efficiency of material thickness measurement.

[0025] For example, in this embodiment, the first detection hole 601 is a rectangular strip hole, which is set in the horizontal direction and its extension direction is the same as the moving direction of the placement mechanism. At the same time, the first detection hole 601 corresponds to the detection section of the detection mechanism in the height direction, so that the detection mechanism can realize the detection function and thus realize multi-point thickness measurement of the material in the linear direction.

[0026] For example, the second detection hole 602 is a circular or arc-shaped through hole distributed in a ring array around the rotation center.

[0027] It is worth noting that in this embodiment, the first detection hole 601 and the second detection hole 602 partially overlap in the moving direction of the placement mechanism. The overlapping area forms a composite detection area, which can achieve both linear measurement and measurement at a certain angle.

[0028] In an exemplary embodiment, the placement mechanism further includes a pressure plate 7, which is provided with a third detection hole 701 and a fourth detection hole 702. The third detection hole 701 is provided in correspondence with the first detection hole 601, and the fourth detection hole 702 is provided in correspondence with the second detection hole 602.

[0029] In this embodiment, a pressure plate 7 is added above the detection plate 6 to form a measurement system with a double-layer detection hole arrangement. When the material to be tested is clamped between the detection plate 6 and the pressure plate 7, the detection beam can sequentially penetrate the combination channel of the third detection hole 701 and the first detection hole 601, or the fourth detection hole 702 and the second detection hole 602, to achieve thickness measurement at different locations of the material. This not only improves the stability of the material fixation but also avoids inaccurate measurement results caused by potential material movement during the detection process.

[0030] For example, in this embodiment, the pressure plate 7 and the detection plate 6 are connected by multiple bolts or screws.

[0031] For example, in this embodiment, after the pressure plate 7 and the detection plate 6 are fixed, there is a certain gap between them, which can prevent the pressure plate 7 from squeezing the material, causing material deformation and affecting the measurement accuracy.

[0032] For example, in this embodiment, an adjustment mechanism can be provided between the pressure plate 7 and the detection plate 6 to adjust the gap between the pressure plate 7 and the detection plate 6 to accommodate different materials.

[0033] In an exemplary embodiment, this application also proposes a detection mechanism including a column 8, a first detector and a second detector, the column 8 being disposed on a base 1, and the first detector and the second detector being located on both sides of the placement mechanism in the vertical direction.

[0034] In this embodiment, the column 8 provides rigid support to ensure the positional stability of the detector during the measurement process. The detectors arranged vertically can detect the thickness of the material, and the thickness value can be directly obtained by calculating the difference for accurate measurement.

[0035] For example, the column 8 can be a hollow steel pipe or a solid metal column, which is fixed to the base 1 by bolts or welding.

[0036] For example, the first detector includes a first mounting block 9 and a mounting plate 901. The first mounting block 9 is detachably connected to the column 8, and the mounting plate 901 is fixedly connected to the first mounting block 9. The first mounting block 9 can be an aluminum alloy module with a snap-fit ​​structure, which can be quickly attached and detached from the column 8 by rotation locking. In a specific embodiment, the column 8 has multiple mounting holes along its length. The first mounting block 9 can be connected to the mounting holes by quick-release nuts, thereby adjusting the height of the first detector. The first detector in this embodiment also includes a first measuring module, which is mounted on the mounting plate 901 and can use a snap-fit ​​structure. The second detector includes a second measuring module. The first and second measuring modules are laser displacement sensors, including but not limited to through-beam laser thickness gauges and U-shaped integrated laser thickness gauges.

[0037] For example, the second detector includes a second mounting block 10 and an adjusting bracket 1001. The second mounting block 10 is detachably connected to the column 8, and the adjusting bracket 1001 is fixedly connected to the second mounting block 10. In this embodiment, the second mounting block 10 and the first mounting block 9 are installed in the same way, both being detachably connected to the column 8. The adjusting bracket 1001 is a three-axis adjusting bracket 1001, and the second measuring module is installed inside the adjusting bracket 1001. This will not be described in detail here. Therefore, the first detector and the second detector achieve laser focusing of the laser displacement sensor.

[0038] It is worth noting that in this embodiment, there are strict requirements for the installation position of the detection mechanism and the detection plate 6. During installation, it is necessary to ensure that the laser emitted by the first detection module and the second detection module can accurately pass through the detection hole group to the material surface.

[0039] In one exemplary embodiment, the driving mechanism includes a motor 5, a linear slide 2, and a slider. The motor 5 is disposed at one end of the linear slide 2, and a screw is provided inside the linear slide 2. The output end of the motor 5 passes through the linear slide 2 and is connected to the screw. The slider is threadedly connected to the screw and is fixedly connected to the fixing plate 4. The linear base 1 is provided with a plurality of support frames 11 for fixing the linear slide 2.

[0040] In this embodiment, the screw is driven to rotate by the motor 5, which in turn moves the slider along the linear slide 2. Since the slider is fixedly connected to the fixed plate 4, the horizontal movement of the placement mechanism is achieved. At the same time, the linear slide 2 and the support frame 11 ensure the straightness and stability of the movement trajectory. Through the cooperation of the motor 5, the screw, and the slider, precise and controllable linear motion is achieved, and the position of the placement mechanism can be adjusted within a large range, thereby achieving the desired thickness of the material at various points in the horizontal direction.

[0041] For example, in this embodiment, the motor 5 can be a stepper motor 5 or a servo motor 5 to achieve precise control of the screw's rotation speed and angle. The linear guide can be a ball linear guide or a sliding linear guide. In this embodiment, a ball linear guide is used, which has higher motion accuracy and lower frictional resistance. The threaded connection between the slider and the screw can be a ball screw structure or a regular thread structure. The ball screw structure can reduce friction and improve transmission efficiency.

[0042] For example, in this embodiment, the base 1 is provided with multiple support frames 11. The top of the support frame 11 is connected to the linear slide 2. The support frame 11 can be made of aluminum alloy or steel and is fixed to the linear base 1 with bolts. The number and spacing of the support frames 11 can be adjusted according to the length of the linear guide rail and the load requirements. The support frames 11 can raise the height of the entire drive mechanism so that the first detector and the second detector are located on both sides of the detection plate 6. In a specific embodiment, the support frame 11 may be provided with adjusting bolts for fine-tuning the levelness and straightness of the linear guide rail.

[0043] In summary, this utility model uses a drive mechanism to move the placement mechanism horizontally, and in conjunction with the rotatable detection plate 6 and the detection mechanism, it achieves a wide range and multi-angle measurement of material thickness in the horizontal and circumferential directions, solving the problems of low efficiency and limited measurement range of traditional measurement methods.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
