Abstract
Description
Technical Field
[0001] This utility model relates to the field of photometer technology, and in particular to a photometer thin film test frame. Background Technology
[0002] Thin-film materials are widely used in displays, packaging, photovoltaics, lighting, and automotive interiors. Their optical properties—including visible light transmittance, haze, reflectivity, optical density, chromaticity coordinates, and scattering characteristics—directly affect the appearance and function of products. Research and development and production processes typically involve quantitative characterization using optical measurement equipment. To obtain stable and repeatable measurement results, a dedicated thin-film testing fixture is required to ensure flat sample clamping, accurate coupling with the optical path, controllable reproduction of incident / detection geometry, and effective isolation from external interference.
[0003] The aforementioned existing technical solutions have the following drawbacks: uneven clamping force, edge stress concentration, or unquantifiable tension, which can easily cause wrinkling, micro-ripples, and in-plane strain, leading to a decrease in the repeatability of transmittance, haze, and reflection measurements. This is particularly evident for ultra-thin, soft, or fragile coating membrane materials. The coaxiality of the test fixture and the instrument's optical axis, the normal relationship between the sample and the beam, and the incident / received angles often rely on manual experience for adjustment. The angle and distance references are lacking, making it difficult to guarantee consistency. Utility Model Content
[0004] The purpose of this invention is to provide a photometer thin film testing fixture to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A photometer thin film testing frame includes a first rectangular block, a second rectangular block, a round rod, and a magnet. The first rectangular block has a first rectangular groove at its rear end on its left side, and a first round hole at its front end. The first round hole has an axis oriented left-right. A protrusion integrally formed to the left is located at the front end of the first round hole, and a first through hole penetrating vertically is located at the top of the protrusion. The axis of the first through hole is vertically aligned. The second rectangular block has a second rectangular groove at its rear end on its right side, and a second round hole at its front end. The second round hole has an axis oriented left-right. A mounting groove is located at the front end of the second round hole, and second through holes penetrating vertically are located at the top and bottom of the mounting groove. The axis of the second through hole is vertically aligned.
[0007] By adopting the above technical solution, the first and second rectangular blocks can be fixedly installed by the round rod. The vertical setting of the axis direction can ensure that the fixing force is directly applied to the upper and lower surfaces of the components, avoiding the generation of lateral component force due to the tilt of the through hole. This effectively improves the structural stability and component positioning accuracy of the test frame during use, and ensures the accuracy and reliability of the photometer thin film test.
[0008] In a further embodiment, the first rectangular block and the second rectangular block are fixedly installed, the round rod is inserted into the first through hole and the second through hole, the axis of the round rod is collinear with the axis of the first through hole and the axis of the second through hole, and the left end face of the first rectangular block is in contact with the right end face of the second rectangular block.
[0009] By adopting the above technical solution, the left end face of the first rectangular block and the right end face of the second rectangular block are fitted together, which can improve the connection rigidity and stability of the overall structure, avoid relative shaking or displacement caused by gaps, and the fitting surface can uniformly transmit the load. The axes of the first through hole and the second through hole are precisely aligned, which facilitates the smooth insertion of the round rod and ensures that the axis of the round rod is collinear with the axes of the two through holes, thereby improving the assembly accuracy and efficiency.
[0010] In a further embodiment, the top and bottom of the first rectangular groove are completely open, and a first waist-shaped hole is provided inside the first rectangular groove, extending from left to right.
[0011] By adopting the above technical solution, the design of the first rectangular groove with its top and bottom completely open facilitates the quick placement and removal of samples. The design of the first waist-shaped hole makes testing more convenient and can also play a buffering and compensation role to a certain extent, thereby enhancing the stability and reliability of the overall structure.
[0012] In a further embodiment, the top and bottom of the second rectangular groove are completely open, and a second waist-shaped hole is provided inside the second rectangular groove, extending from left to right.
[0013] By adopting the above technical solution, the design of the second rectangular groove with its top and bottom completely open facilitates the quick placement and removal of samples. The design of the second waist-shaped hole makes testing more convenient and can also play a buffering and compensation role to a certain extent, thereby enhancing the stability and reliability of the overall structure.
[0014] In a further embodiment, a magnet is fixedly installed inside the first circular hole.
[0015] By adopting the above technical solution, the magnet can generate a strong magnetic field attraction, which can quickly and firmly adsorb and connect with other components containing ferromagnetic materials without the need for additional mechanical fixing structures, simplifying the installation process while ensuring the reliability of the connection. It is especially suitable for scenarios that require frequent disassembly or temporary fixation. The magnet can adapt to a variety of working environments and can maintain stable magnetism and performance within a certain temperature and humidity range.
[0016] In a further embodiment, a magnet is fixedly installed inside the second circular hole.
[0017] By adopting the above technical solution, the magnet can generate a strong magnetic field attraction, which can quickly and firmly adsorb and connect with other components containing ferromagnetic materials without the need for additional mechanical fixing structures, simplifying the installation process while ensuring the reliability of the connection. It is especially suitable for scenarios that require frequent disassembly or temporary fixation. The magnet can adapt to a variety of working environments and can maintain stable magnetism and performance within a certain temperature and humidity range.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. By setting up the round rod, the first rectangular block, and the second rectangular block, the first rectangular block can rotate along the round rod.
[0020] 2. By fixing magnets inside the first and second rectangular blocks, the first and second rectangular blocks can be opened / closed quickly.
[0021] 3. The fact that the top and bottom of the first rectangular groove and the second rectangular groove are completely open makes it easier to fix the sample. Attached Figure Description
