[0002] A thin film thickness gauge is a specialized instrument designed to measure the thickness of various thin film materials. It is mainly divided into two categories: contact and non-contact. It is widely used in many industries, including but not limited to packaging, plastics processing, and electronics. With technological advancements, different types of thin film thickness gauges have emerged to meet various needs in laboratory research. However, traditional thin film thickness gauges have several limitations in design and use, mainly in the following aspects:

[0003] Traditional thin film thickness gauges are relatively bulky. Due to their sophisticated optical or mechanical structures, these devices often need to be fixedly installed on a specific operating table and powered by a fixed power supply. They are difficult to move and carry, and are generally placed in the laboratory for testing.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this utility model.

[0029] Example 1

[0030] like Figure 1 As shown, a portable thin film thickness testing device includes: a base plate 1, a vertical plate 2, and a modular assembly for film thickness testing.

[0031] The upright plate 2 is vertically installed at one end of the base plate 1, and the other end of the base plate 1 is the sample stage, on which the thin film sample 11 to be tested is placed; the film thickness testing modular component is fixedly installed on the side of the upright plate 2.

[0032] The overall film thickness testing device adopts a compact three-dimensional structure, integrating the base plate 1, the vertical plate 2, and the modular film thickness testing components together, reducing the overall size and floor space, making the equipment more portable and mobile. The modular components are parts of the device that can be independently manufactured, tested, and replaced, making the device more flexible, easier to maintain, and easier to upgrade.

[0033] Specifically, the modular component for film thickness testing includes a guide rail 6, a slider 4, a main unit 8, and a sensing probe 10;

[0034] The guide rail 6 is fixed vertically to the side of the upright plate 2; the slider 4 is slidably connected to the guide rail 6; the main unit 8 is connected to the guide rail 6 through the slider 4, which is used to drive the main unit 8 to move up and down on the guide rail 6; the sensing probe 10 is fixedly installed at the lower end of the main unit 8.

[0035] The modular component for film thickness testing also includes a sensor and a memory (not shown in the attached diagram).

[0036] In this embodiment, the sensor and sensing probe 10 are a high-precision integrated structure, which can be replaced with different models according to the material of different thin film samples 11 to be tested, such as optical sensors, laser sensors, inductive sensors, or others, to perform thickness sensing tests through different forms of signals such as light, electromagnetic, or eddy current. This integrated structure is electrically connected to the memory and is installed inside the host 8; the signal input terminal of the sensor is integrated with the sensing probe 10, and the signal output terminal is electrically connected to the host 8 to transmit the test data to the host 8 and save it in the memory.

[0037] In this embodiment, the sensing probe 10 also has wear-resistant and scratch-resistant properties, and the sensor's method of acquiring thickness data and the storage of the memory are both implemented using existing technologies.

[0038] In this embodiment, the sensing probe 10 is detachably mounted on the lower end of the host 8 via a threaded interface and faces the thin film sample 11 to be tested on the sample stage. It can contact the thin film sample 11 to be tested and test its thickness, or it can be tested in a non-contact manner (for example, non-contact testing can be performed when using an optical sensor).

[0039] The upright plate 2 is equipped with a pressing shaft 7, a return spring 5 and a drive pin 3.

[0040] The pressing shaft 7 is installed inside the upright plate 2. The top diameter is larger than the middle and bottom diameters. The top extends outside the upright plate 2. The middle outer side is fitted with a return spring 5. A drive pin 3 is provided on one side of the bottom. The return spring 5 is located between the pressing shaft 7 and the upright plate 2 and is elastically connected to them. The drive pin 3 is installed in the assembly hole and connected to the slider 4 to realize motion transmission.

[0041] Specifically, when the pressing shaft 7 is pressed, the pressing shaft 7 moves downward. The displacement of the pressing shaft 7 causes the return spring 5 to compress and deform. At the same time, the drive pin 3 on the pressing shaft 7 is connected to the slider 4, so that the slider 4 moves downward along the guide rail 6 under the guidance of the guide rail 6. The slider 4 is pressed down with the pressing shaft 7, so that the sensing probe 10 contacts the thin film sample 11, triggering the sensor to perform thickness testing. After the test is completed, the pressing shaft 3 is released, the return spring 5 is reset, and the pressing shaft 7 pulls the slider 4 back to the initial position.

[0042] The main unit 8 is equipped with a display screen 12 and operation buttons 13.

[0043] The display screen 12 is used to display the thickness of the thin film sample 11 to be tested; the operation buttons 13 include a power button, a calibration button, a zeroing button, and directional buttons. The directional buttons can be used to navigate in the menu or select different measurement modes.

[0044] The main unit 8 has a battery compartment 9 on its back, which is fixedly connected to the main unit 8 with screws; the battery compartment 9 contains at least one battery, which is electrically connected to the main unit 8 to power the device. The independent power supply means that the device can be powered without relying on an external or fixed power source, making it easy to carry.

[0045] The base plate 1 and the upright plate 2 are made of corrosion-resistant and wear-resistant materials, employing a lightweight design while ensuring structural strength. In this embodiment, compared to traditional testing instruments, lightweight yet robust aluminum alloy or high-strength plastic is selected to improve portability and durability.

[0046] A shock-absorbing pad 14 is provided at the bottom of the base plate 1. The shock-absorbing pad 14 is fixed to the bottom surface of the base plate 1 by adhesive to maintain the stability of the device. In this embodiment, the shock-absorbing pad 14 is made of silicone or rubber and has a thickness of 3-5mm.

[0047] The portable film thickness testing device is also equipped with a portable storage case, the inside of which has a fixing slot that matches the shape of the portable film thickness testing device. In this embodiment, the storage case is only about 30 centimeters long, small enough to be easy to carry.

[0048] In this embodiment, the detailed steps of the working method of the portable thin film thickness testing device are as follows:

[0049] S1. Before powering on: Take the device out of the storage box, place the device stably, wipe the detection platform with an alcohol wipe, and press the power button on the main unit to power on;

[0050] S2. Before testing: After powering on, press the pressing shaft to check if the thickness data displayed on the screen is 0; if it is 0, insert the standard film to check if the test data is accurate; if the data is accurate, the sample can be tested.

[0051] S3. During the test: S301: Place the film sample to be tested on the sample stage of the base plate, and try to ensure that the sample is flat and wrinkle-free; S302: Press the pressing shaft until the induction probe contacts the film sample to be tested and test the data; S303: Move the film sample to be tested to perform multi-point testing and measure the maximum, minimum and average thickness data of the sample.

[0052] S4. After testing: After the test is completed, press the power button to turn off the device and put it into the storage box.

[0053] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
